bug#38014: 26.3.50; [PATCH] * makefile-edit.el: regexp-quote the param in makefile-move-to-macro to avoid error message

[lin.sun]

[PATCH] * makefile-edit.el: regexp-quote the param in
makefile-move-to-macro.

Fix the error message from `makefile-move-to-macro' when there is '$'
or '\\' in param for re-search-forward, with `(global-ede-mode t)' and
`(semantic-mode t)'. Enable ede and semantic mode, then open a
Makefile.am in which has line 'AM_LIBTMP_LIBS:=$(shell X \--libs)'
will trigger this issue.
